+企业微信会话存档SDK（基于企业微信C版官方SDK封装），暂时只支持在`linux`环境下使用当前SDK。
+
+### 官方文档地址
+https://open.work.weixin.qq.com/api/doc/90000/90135/91774
+
+### 使用方式
+
+1、安装 go module
+> go get -u github.com/silenceper/wechat/v2
+
+2、从 `github.com/silenceper/wechat/v2/work/msgaudit/lib` 文件夹下复制 `libWeWorkFinanceSdk_C.so` 动态库文件到系统动态链接库默认文件夹下，或者复制到任意文件夹并在当前文件夹下执行 `export LD_LIBRARY_PATH=$(pwd)`命令设置动态链接库检索地址后即可正常使用
+
+### Example
+
+```go
+package main
+
+import (
+	"bytes"
+	"fmt"
+	"github.com/silenceper/wechat/v2"
+	"github.com/silenceper/wechat/v2/work/msgaudit"

+	if err != nil {
+		fmt.Printf("SDK 初始化失败：%v \n", err)
+		return

+

+	chatDataList, err := client.GetChatData(0, 100, "", "", 3)
+	if err != nil {
+		fmt.Printf("消息同步失败：%v \n", err)
